Monitor Menu
View Statistics
The View Statistics menu (Figure 17) displays the performance of the drives and their
corresponding level of hierarchy. The throughput of the drives is displayed in KB/s (KiloBytes per
second) and IO's (I/Os per second, number of IO's on the controller). The performance figures
reflect the load on the controller and not necessarily the maximum performance the controller can
deliver.
When selecting a drive's statistics, StorCon displays a list of all drives for a particular RAID level
(for this example the physical drive for RAID level 1). In addition to the performance report on the
drives, the menu monitor displays the hard disk I/O channel, hard disk ID, hard disk name and hard
disk gross capacity (1MB = 1024KB). See Figure 18. The figures shown at TOTAL represent the
performance of the host drives as a whole. With the left arrow and right arrow keys you may
change the scale of the graphical KB/s indication. With the up arrow and down arrow keys you can
scroll the screen to see additional Drives (if available).
Use "Cache Statistics" to view the utilization of the Intel RAID Controller SRCMR's caches, (read
cache and write cache). This menu also displays the size of the cache in KB and the settings of
both caches (on, or off). The figures for "cache hits" show how often requests can be serviced out
of the cache, for example, without triggering an immediate disk IO.
